2.17 FUEL LEVEL SYSTEM OPERATION
The fuel level system operates automatically, once the 'FUEL LEVEL
SYSTEM CALIBRATION' has been performed. The indicator displays a
left, center, and right digital read-out of the units of fuel remaining of up
to 99 units per tank. Additionally the left and right displays are also
presented graphically to show percentage of fuel remaining for quick
reference.
************************* WARNING **********************************
AIRCRAFT ATTITUDE AND OTHER FACTORS CAN AFFECT THE
ACCURACY OF THE FUEL LEVEL READINGS. AFTER
INSTALLATION AND PERIODICALLY THEREAFTER, VERIFY THAT
THE SYSTEMS ACCURACY IS ACCEPTABLE FOR YOUR
INTENDED USE.
**************************************************************************
If a probe is not installed or not functioning, that display is blanked. An
unsteady display value should be suspect and possibly disregarded as
faulty operation.
Fuel Level Alert: A low fuel level alarm has been incorporated into the
system which signals you when a minimum fuel level has been reached
in a given tank by displaying 'Lo' in the corresponding display area. This
value is picked at our factory but may be specified upon written request
at the time fuel calibration information is submitted to us.
2.18 FUEL LEVEL SYSTEM CALIBRATION
The fuel level system needs to be calibrated to your fuel tank. The
procedure is very easy to perform, but will take a little while to do
accurately.
TIPS:
Sloshing the tanks with fuel before performing calibration can
result in a better eventual calibration as various contaminants etc.
will be flushed from the tanks and probes.
You can do all tanks simultaneously by adding fuel increments to
each of them and following the step by step instructions.
